From e18997ed95bfda937d75bd4a68b881baad996afa Mon Sep 17 00:00:00 2001 From: Paul Bailey Date: Sun, 16 Nov 2025 16:15:42 +0000 Subject: [PATCH] feat: implement location selection interface with EXIF, GPS, and map picker - Created LocationSelector component with three location input methods: * Auto-populate from photo EXIF data * Device GPS location capture with accuracy indicator * Interactive Leaflet map picker with draggable marker - Added Ireland coordinate validation (lat: 51.4-55.4, lng: -10.5--5.5) - Created coordinate utility functions for validation and formatting - Added LocationSelectorDemo page for testing at /demo/location-selector - Displays selected location with coordinates, source, and accuracy - Provides clear error messages for validation failures - Satisfies requirements 1.1, 1.2, 1.3, 8.2 --- .kiro/specs/beach-litter-mapping/tasks.md | 2 +- src/App.tsx | 13 +- src/components/report/LocationSelector.tsx | 337 +++++++++++++++++++++ src/components/report/README.md | 73 +++++ src/components/report/index.ts | 1 + src/pages/LocationSelectorDemo.tsx | 105 +++++++ src/pages/index.ts | 1 + src/utils/coordinates.ts | 70 +++++ src/utils/index.ts | 14 +- 9 files changed, 601 insertions(+), 15 deletions(-) create mode 100644 src/components/report/LocationSelector.tsx create mode 100644 src/pages/LocationSelectorDemo.tsx create mode 100644 src/utils/coordinates.ts diff --git a/.kiro/specs/beach-litter-mapping/tasks.md b/.kiro/specs/beach-litter-mapping/tasks.md index 1fe1174..2a9d1cb 100644 --- a/.kiro/specs/beach-litter-mapping/tasks.md +++ b/.kiro/specs/beach-litter-mapping/tasks.md @@ -49,7 +49,7 @@ - Handle multiple photo uploads - _Requirements: 1.2, 1.3, 1.4, 1.5, 8.3_ -- [ ] 7.
